Main Functions

Prohexadione-Calcium 15% WP is mainly used to:

• Reduce excessive shoot growth
• Support canopy management
• Improve light and air movement through the canopy
• Help maintain a more compact crop structure
• Support a better balance between vegetative growth and productive growth

Its strongest practical value is in crop programs where excessive vigor makes canopy management, spray penetration, orchard structure, or row visibility more difficult.

Mode of Action

Prohexadione-Calcium works by inhibiting gibberellin biosynthesis. Gibberellins are closely linked to shoot elongation and vegetative growth, so when their formation is reduced, shoot extension slows and the crop develops a more compact structure. That is why this active ingredient is used in programs that need growth regulation rather than additional vegetative stimulation.

Suitable Crops and Application Areas

The strongest crop directions for Prohexadione-Calcium 15% WP include:

• Apple
• Pear
• Cherry
• Strawberry
• Peanut
• Grass grown for seed
• Watercress

This crop range shows the product’s main use pattern clearly: it fits programs where shoot-growth reduction, canopy balance, and easier crop-structure management are important. Final crop scope should follow the approved local label in the destination market.

Application Guidance

Prohexadione-Calcium 15% WP should be used according to the approved local label. Timing is important because this product is designed to regulate active vegetative growth, not to correct crop structure after the main growth stage has already passed.

In general, this formulation is suitable when:

• the crop shows excessive vegetative growth
• shoot extension control is needed
• the canopy needs better light and air penetration
• the crop program requires a growth-regulating plant growth regulator

Final timing, dosage, interval, and crop-specific directions should follow the approved local label.

Formulation Features

WP means wettable powder. This is a dry formulation that forms a spray suspension after mixing with water. In practical use, Prohexadione-Calcium 15% WP is a powder-format plant growth regulator suited to standard agricultural spray preparation in orchards, fields, and other registered crop systems.

The 15% concentration gives this formulation a higher-loading powder specification within the prohexadione-calcium line while keeping the traditional wettable-powder route.

Product Advantages

Prohexadione-Calcium 15% WP stands out for these reasons:

• Clear vegetative growth control function
• Gibberellin biosynthesis inhibition
• Strong fit for canopy management
• Useful in fruit-tree and other registered crop programs
• Traditional WP dry formulation
• Higher concentration than the 10% WP version

Its strongest product value is simple: Prohexadione-Calcium 15% WP helps reduce excessive shoot growth and supports a more manageable canopy structure in registered crops.

Safety and Use Precautions

Prohexadione-Calcium 15% WP should be handled carefully during mixing, spraying, storage, and transport. It should be used according to the approved local label and standard agricultural safety practice.

Important points include:

• keep away from food, feed, and drinking water
• avoid contamination of water bodies and non-target areas
• wear proper protective clothing, gloves, and face protection
• follow local requirements for spray timing, drift, and crop-use directions
• use only according to the approved local label

Storage and Transport

Store Prohexadione-Calcium 15% WP in the original sealed package in a cool, dry, and well-ventilated place. Keep it away from direct sunlight, moisture, heat sources, food, feed, and unauthorized access. Because this is a powder formulation, the packaging should be protected from:

• Humidity
• Water exposure
• Bag damage
• Rough handling during transport

Good storage helps keep the powder in stable condition before use.

FAQ

What is Prohexadione-Calcium 15% WP best known for?

It is best known as a plant growth regulator for vegetative growth control, canopy management, and shoot-growth suppression.

Is this mainly a growth-retardant product?

Yes. Its strongest and clearest use direction is growth control, not general growth stimulation.

What crops is it commonly used in?

The clearest crop fit includes apple, pear, cherry, strawberry, peanut, grass grown for seed, and watercress under registered use directions.

What does WP mean in Prohexadione-Calcium 15% WP?

WP means wettable powder.

What is the practical value of the 15% WP formulation?

It provides a higher-concentration traditional powder route for crop programs that already use wettable-powder plant growth regulators.
